Then you're probably overrating Valaciunas. Calderon is probably not going to be here beyond this season anyway and Valanciunas hasn't proven anything yet. It's tough to trade Val, but it's tough to not land Harden imo.

Lowry, Harden would be one of the best back courts in the NBA imo.

I could live with this lineup, then look to get a Center next summer (including Aldrich since he was a throw in w/Houston):

Valanciunas hasn't proven anything yet? I think that's a poor statement. The kid has been dominant in a strong league as a teenager and dominated his under-19 and 20 tournies as well. He's come over looking decent as a 20 year old and it's not difficult to foresee a possible longterm and successful career with what he's shown. As far as trading a skilled, young, athletic seven footer for a guy that was the third and maybe fourth best player on his team his team while coming off of a very inconsistent playoff showing, I'm not sure it's a good decision given that you'd have to max out the guy you're getting in addition to most not considering him a max guy.
